Description

Technical Field

[0001] The utility model relates to the technical field of slip rings, in particular to a slip ring integrated component. Background Art

[0002] Display Port (DP for short) is a digital video interface standard developed by a PC and chip manufacturer alliance and standardized by the Video Electronics Standards Association (VESA) for simultaneous transmission of audio and video. With the development of high-definition images and high-definition displays, the ultra-high bandwidth and resolution of the DP interface are fully sufficient to adapt to the development of high-definition display devices, and the demand for DP cables has also increased. HDMI stands for High Definition Multimedia Interface, which is a fully digital video and sound transmission interface that can send uncompressed audio and video signals. With the development of high-definition images and high-definition displays, more and more electronic devices have integrated HDMI ports, which can transmit 2K, 4K and above high-definition video transmission. With the emergence of high-definition video and TB-level storage devices, higher bandwidth and transmission rate have become a necessity. USB 2.0 provides sufficient bandwidth for a variety of devices and applications, so USB2.0 has also been widely used in conductive slip ring communications, but the transmission rate of 480Mbps has limited the development of high-speed communication. The new generation of USB3.0 standard provides a theoretical transmission rate of 5Gbps. The USB3.0 communication slip ring developed on this basis can realize data transmission between the rotating platform and the stationary platform, providing the best technical solution for solving the problem of large-capacity data and signal transmission between rotating connected system components. At present, the design schemes of high-speed signal slip rings include: single signal slip ring, which cannot integrate multiple signals at the same time; or using smaller slip rings for design.

[0003] The existing slip ring integrated assembly has a relatively single product application environment during use, and is designed with a smaller slip ring, which limits the size of the slip ring and makes it inconvenient to use. Therefore, in view of the above situation, it is urgent to develop a slip ring integrated assembly to overcome the shortcomings in current practical applications. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0027] See also Figure 1-Figure 7 , an embodiment of the utility model provides a slip ring integrated assembly, the slip ring integrated assembly comprising: a slip ring 1 and a slip ring 2;

[0028] The slip ring 2 is nested outside the slip ring 1, and the slip ring 1 and the slip ring 2 are linked by a transition piece between them.

[0029] The slip ring 2 is provided with a through hole for the wire of the slip ring 1 to pass through.

[0030] In an embodiment of the present invention, the rotor parts of the slip ring 1 and the slip ring 2 are both copper ring structures.

[0031] The copper ring diameter of the rotor part of slip ring 1 is smaller than that of the rotor part of slip ring 2. Among them, slip ring 1 is designed to be smaller, and the copper ring diameter of the rotor part of the slip ring is smaller, which can reduce its loss and make it have a higher transmission bandwidth, meeting the high-speed transmission requirements of VR application video signals.

[0032] In one embodiment of the utility model, the copper ring used in the rotor part of the slip ring 2 is a through-hole structure, the rotor of the slip ring 1 is fixed to the hole of the slip ring 1 through a connecting piece, and the signal line of the slip ring 1 passes through the through-hole; wherein the connecting piece adopts a baffle structure, which is used to connect the rotor tail of the slip ring 2 and the rotor top of the slip ring 1, so that the slip ring 2 can drive the slip ring 1 to rotate together when rotating, such as Figure 7 shown.

[0033] The cap sleeve arranged on the slip ring 2 completely nests the slip ring 1 inside to form an integral whole.

[0034] In one embodiment of the utility model, a high-speed signal line is placed on the slip ring 1, and a functional scattered line is placed on the slip ring 2.

[0035] The number of the high-speed signal lines is five pairs, and the number of the functional discrete lines is four, wherein each pair of high-speed signal lines includes a differential line and a clock signal line, and the differential line and the clock signal line maintain a twisted pair structure inside the slip ring 1.

[0036] By setting up slip ring 1 and slip ring 2, since high-speed signals can be transmitted stably, the most important thing is to reduce losses. The smaller the size of the slip ring, the smaller the loss. According to the theoretical knowledge of transmission lines, the loss of the slip ring is related to the aperture (diameter) size of the copper ring and the frequency of the passing signal. The aperture size of the slip ring and the signal frequency determine whether the slip ring can transmit signals.

[0037] Therefore, the slip ring is divided into two slip rings on the main body, which we call slip ring 1 and slip ring 2. Slip ring 1 and slip ring 2 are two independent slip rings, and the two slip rings are linked by an adapter in the middle. Slip ring 2 is nested outside of slip ring 1, and has a through hole to allow the wire of slip ring 1 to pass through, such as Figure 1 shown.

[0038] Among them, slip ring 1 adopts a smaller design, and the copper ring of the slip ring rotor part has a smaller diameter, which can reduce its loss and make it have a higher transmission bandwidth to meet the high-speed transmission requirements of video signals.

[0039] The rotor part of slip ring 2 is a large copper ring with a through-hole structure. The rotor of slip ring 1 is fixed to the hole of slip ring 1 through a connector, and the signal line of slip ring 1 passes through the through-hole. The cap sleeve of slip ring 2 is designed to be extended to completely nest slip ring 1 inside, forming an integral whole. Figure 2 shown.

[0040] From the above main factors that determine the slip ring loss, it can be seen that the size of the slip ring has a great influence on the transmission of high-speed signals. Therefore, when designing and integrating this project, a large slip ring is used to integrate a small slip ring; the small slip ring 1 is used for high-speed transmission cable pairs of various signals, and the large slip ring 2 is used for the remaining functional lines or other types of signals; Figure 3 shown.

[0041] like Figure 5 As shown, the USB3.0 Cable is composed of 2 power lines, a pair of USB2.0 data lines, 2 pairs of high-speed lines, and 1 shielded line, for a total of 11 lines.

[0042] Table 1 USB3.0 wire pin definition

[0043]

[0044]

[0045] like Figure 6 As shown, HDMI Cable is composed of 5 pairs of high-speed data lines (1 twisted pair + 1 shield), plus 4 functional lines and 1 ground line, a total of 20 lines;

[0046] The structure of DP cable is roughly the same as that of HDMI cable: 5 pairs of high-speed data lines (1 twisted pair + 1 shield), plus 5 functional lines and 1 ground line, a total of 21 lines.

[0047] Among them, 2 pairs of high-speed lines in USB3.0 and 5 pairs of high-speed lines in HDMI / DP are arranged on slip ring 1, and the remaining cables are placed on slip ring 2. This will better reduce signal loss and make transmission more stable.

[0048] The slip ring of the utility model adopts a large slip ring integrated with a small slip ring, which reduces the loss of high-speed signals and can stably transmit DisplayPort (or HDMI) video signals and USB3.0 signals, etc., solving the problem of simultaneous transmission of multiple high-speed signals without interference.

[0049] In addition, the slip ring uses the slip ring lead to connect with the video cable. Correspondingly, the same line connection is defined. Each group of high-speed signal lines is shielded separately with aluminum foil wrapped on the outside. After all the lines are connected, they are shielded with aluminum foil and shielding net on the outside, and then wrapped with outer cover. The shielding quality of the external wiring part is directly related to the quality of the slip ring transmission signal. It is necessary to refer to the cable structure for shielding.

[0050] It should be noted that, in the present invention, unless otherwise clearly specified and limited, the terms "slide", "rotate", "fix", "have" and the like should be understood in a broad sense, for example, it can be a welding connection, a bolt connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
